Suspension cracking noise Volkswagen Passat 7
Check Volkswagen Passat 7 suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Passat 7, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are dead, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To examine if this is the issue that worries you, take a dented road and focus on the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them as soon as possible or you may ruin other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Volkswagen Passat 7 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a sound when they are in torsion. To examine this, you can try both types of torsion, first vertical with suspension compressions on the speed bump passages, and horizontal when you are going to make a turn at low speed. If it cracks in these two situations you should consider changing it or them.

The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to examine it, position it under the car and apply twists on each of its elements to examine that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Volkswagen Passat 7, it is possible that it is the stabilizer bar itself that is concerned.

Bear in mind to examine by passing under your car the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case disassemble them from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a noticable weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Volkswagen Passat 7.
